1. How to reset the administrator password?

Turn the NVR from the front to the back, find a red button, use the reset needle to aim at the red button and press it for about 5 seconds. You will hear a "ding" sound, indicating that the reset is successful. At this time, the NVR will automatically restart. After the NVR restarts and displays the login interface, enter the default administrator password "888888" and click the login button to log in.
